Honest Ed's is a real discount superstore located on the corner of Bloor and Bathurst Street in Toronto, and spans the whole block. It was established in 1948 and was run by "Honest Ed" for nearly 60 years before his death.
The store is used as a fight venue selected by Envy Adams in Volume 3 for Scott and Todd Ingram to fight their way through. The stipulation set is that Todd isn't able to use his vegan powers, and the first one through the store is declared the winner. Todd manages to make a machine gun out of various bargain items, and Scott loads up on eye protection and armour, but it all falls apart when Todd loses control of his powers and Honest Ed's ends up exploding. The match is called a draw, and the episode continues.
